FLlEFil SPECIFICATION forming part of Letters Patent No. 77 3,268, dated October 25, 1904.

Application led September 19, 1903. Serial No. 173,800. (No model.)

lo @Z whom it may concern:

Be it known that I, HARRY SPENCE, a citizen of the United States, residing at Sanford, in the county of York and State of Maine, have invented an Improvement in Fliers, of which the following description, in connection with the accompanying drawings, isa specification, like numerals on the drawings representing like parts.

IO This invention relates to fliers for spinning or twisting machines, and has for its object to provide a novel construction of iier which can be run at an increased rate of speed without affecting the quality of yarn being spun.

As iiiers are commonly constructed they are made with oppositely-disposed flier-arms, about one of which the yarn is wound to give it the necessary tension and each of which carries at its end an eye or twizzle through which 2O the yarn is led to the bobbin. In attempting to run this type of flier at a high speed it has been found that the centrifugal action of the eyes causes said eyes to spread. To remedy this, it has been customary to make the arms suiiiciently heavy to withstand the centrifugal force of the eyes. This, however, places too much of the weight of the flier in the arms and makes too heavy a iiier to be run at an extremely high speed without vibration. The

attempt to eliminate one evil, therefore, has

only introduced a nother.

In the spinning of some yarns itis extremely important that the drag on the bobbin should be perfectlyuniform-a condition which is defeated if the flier or spindle have any vibration. I/Vith the fliers as previously constructed, therefore, the speed at which they could be run has been limited, because an increase in the speed causes sucient vibration in the parts to affect the quality of the yarn.

This invention is designed to overcome the above objections by providing a flier which has but little weight and is provided with means to absolutely preventthe spreading of the eyes or arms by centrifugal actionfeven when the flier isrunning at an extremely high rate of speed. Having reduced the weight of the Hier and at the same time prevented the arms or eyes from being thrown outward by centrifugal force, I can run my flier at a much higher rate of speed than an ordinary flier without producing any vibrations in either the ier or spindle. I accomplish these ob- I jects by separating the eyes from the flierarms and mounting' said eyes upon an eye-sup- 55 porting member separate from the arms and which is constructed to prevent the eyes from being spread by centrifugal force. Since the arms do notsupport the eyes,and consequently do not have to withstand the centrifugal force on said eyes, they can be made very light, thus reducing to a minimum the weight of the flier.

In the drawings is illustrated one embodiment of my invention.

Figure lis an elevation of aspindle having one form of my improved flier applied thereto. Fig. 2 is a section on the line m m, Fig.

1. Fig. 3 is a modification.

The iiier can be used in connection with any usual form of bobbin, and as herein illustrated it is used in connection with a shuttle-bobbin.

3 designates a bobbin of any usual description carried by a suitable spindle 4, and in the present form of my invention my improved iiier is applied to and supported on the upper end of said spindle.

5 designates the flier-arms, about one of which the yarn is wound to produce the necessary tension therein, and 6 designates the eyes at the ends of the arms, through one of which 8O the yarn is fed to the bobbin, as usual. The eyes 6 are separate from the arms and in this form of my invention are supported by an eyesupporting member 7, having the form of a substantially conical shell secured to or integral with the head of the iier, which is secured to the end of the spindle. The shell 7 may be made of some suitable metal or of tough and light fibrous material or any other suitable material which will hold its shape when the flier is in use. The eyes 6 are illustrated as being secured to the base or lower portion of the shell 7 and in a position adjacent to the free or lower ends of the arms 5. The arms may be either supported directly from the head 8 or secured to the sides of the shell, as

ver: 773,268

seen in Fig. 1, said arms being separated slightly from the shell, so that the yarn can be readily wrapped or wound thercabout. The function performed b y the flier-arms is twofold. In the lirst place, they serve as tension devices for the yarn, and. in the second place, they serve to lead yarn to the eye. It is well known that in the spinning' operation it-is necessary to give the yarn a uniform tension as it is wound on the bobbin, this tension usually being' secured by winding' or wrapping the yarn several times about one of the fiicr-arms. In my improved flier I employ the flier-arms for this same purposcthat is, as a means for giving the necessary tension to the yarn. The arms also serve to lead the yarn to the eye, as seen in Fig. 1. Since the eyes 6 are secured to the rim or base of the shell, it is impossible for them to be displaced by centrifugal action, as they are tied together by an annular member, and since the flier-arms are relieved of strain due to the centrifugal force of the eyes said arms can be made very small and light.

The total weight of a iiier constructed in accordance with my invention is much less than that of an ordinary iiier. To still further reduce the weight, I may, if desired, cut away the shell at its lower portion, as shown at 10, suoli cutting' away of the shell reducing the weight without appreciably weakening the shell.

I prefer to attach the arms 5 to the shell some distance below the upper end thereof, so to leave the said upper end 11 clear of projecting portions and provide a smooth substantially cylindrical surface which the operator may grasp when it is desired to bring the flier to a standstill.

The stopping of an ordinary iiier by engaging one of its arms, as is commonly done, is extremely liable to throw the spindle or iiier out of true. With my improvements, however, the hand of the operator acts as a frictional brake upon the surface 11 and the retarding movement is not applied at a single point, as in the case where it is applied to one of the arms, as above described.

In Fig. 3 I have illustrated my improved flier as adapted to my high-speed spinningmachine set forth in my copending application, Serial No. 126,407, h'led October' 8, 1900. In this embodiment the head or cap 8 of the flier has applied thereto the disk l2, which runs in the bearing 13, as in said application.

IVhile I have illustrated one form in which my invention may be embodied, I do not wish to be limited to this construction, for as I believe I am the first to construct a iiier with eyes separate. from the Hier-arms I desire to claim this broadly. It will be obvious, therefore, that various ways of mounting the eyes separate from their Hier-arms may be employed without departing from the invention.

Having' described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a Hier, a fiier-arm, an eye to lead the yarn from the arm to the bobbin, and means separate from the arm to support the said eye.

2. In a flier, a flier-arm, an eye adjacent the end thereof, and means separate from the arm to support the said eye.

3. In a flier, a Hier-arm, an eye adjacent the end thereof, and an eye-supporting member separate from the arm.

4. In a iiier, Hier-arms, eyes adjacent the ends of said arms and means separate from the arms to prevent the eyes from spreading under the iniiuence of centrifugal force. y

A iiier having flier-arms and eyes adjacent the end thereof but supported independ ently of said arms.

6. In a flier, flier-arms, a substantially conical shell and eyes secured to said shell adjacent the ends of the arms.

7. In a flier, a substantially conical shell, flier-arms secured thereto, and eyes also secured to said shell independently from the arms.

8. Ina flier, a substantially conical shell, iiier-arms secured thereto and eyes also secured to said shell, said eyes being' separate from the arms and situated adjacent the ends thereof.

9. In a Iiier, a substantially conical shell adapted to be secured to a spindle, Hier-arms secured to said shell below the top thereof, and eyes also carried by said shell at the base thereof, said eyes being separate from but adjacent to the ends of the arms.

10. In a flier, a substantially conical shell, an eye supported thereby, and a iiier-arm independent from said eye and also supported by said shell, said fiier-arm extending substantially parallel to the shell and terminating adjacent the eye.

l1. In a iiier, a shell, an veye secured thereto, and a tension device independent from the eye and secured to the shell below the top thereof.

In testimony whereof I have signed my name to this specification in the presence of two sul scribing witnesses.
